Abstract (en)
A technique for reducing multipath distortion in a mobile FM receiver (900) with a plurality of antennas is accomplished through a number of steps. Initially, a first antenna signal and a second antenna signal are received. The first antenna signal is weighted with a variable first weight (W_1K) and the second antenna signal is weighted with a variable second weight (W_2K). The weighted first antenna signal and the weighted second antenna signal are then combined to provide a combined received signal (Y K ) having a combined signal level (LEVEL). The variable first and second weights (W_1k,W_2k) are determined by an adaptation strategy that is substantially controlled by a first algorithm, when the combined signal level (LEVEL) is greater than a predetermined signal level. When the combined signal level (LEVEL) is less than the predetermined signal level, the variable first and second weights (W_1k,W_2k) are determined by an adaptation strategy substantially controlled by a second algorithm.
